Does someone knows how to dissamble this printer to repair the PK/MK switch because of the ink globs it gives on paper ?

Actually I am tired of executing cleaning cycles and wasting ink all the time because of this fawlty switch design in my second R3000 printer. What about the P600: is this design flaw finally fixed ? If so I might buy a P600 and throw away this headache causing printer.

After opening the link click the green download button almost at top of the page:

This opens a new page, check the "I'm not a robot" or what it might be called in your language. After a green checkmark appears click the green download button and the download should start. I hope this helps.

While you're at it replace the ink damper for the blacks, that seems to be the actual problem for the "ink globs" just replacing the switch valve wont fix the problem. Few months ago I replaced the valve switch on my R3000 and 3800 and the ink continued leaking wasn't until I replaced the ink damper for the MK/PK that the problem got resolve.

Thanks for the information. Actually I don't have much time to do this. I might end with buying an P600 in the end if this printer has finally solved this flimsy design fault causing ink dropped on paper.

Sorry to disappoint you but the P600 uses the same damper system.

I find it pity that Epson does not make an hybrid P400/P600 printer: both printers use the same print head, but different ink configuration. The P400 does not have light colors, which is optically not necessary thanks to the variable droplet technology, the light colors can mimicked by smaller ink droplets and by doing so the amount of ink dropped on paper is also dramatically reduced to achieve the same effect. The gloss optimizer equals any gloss difference that still exist on the P600 depending on the print made. The combined printer can be called the P500 using the P600 case and the following ink configuration: gloss optimizer (taking the place of the MK and PK combined to yield a high capacity 60 ml XL cartridge), MK, PK, LK, C, VM, Y, R. The LK will yield ABW prints and the R is from the P400, yielding better oranges and purples and skin tones. In the end: no need of switching valves, no ink spilled by switching between MK/PK, lower ink usage because no LLK, LVM, LC (compensated by smaller and variable droplet technology like the P400).

Someone who can reprogram the Epson P600 to use the aforementioned ink configuration or using an RIP ???
